THE INFLUENCE OF THERMAL STRESS OF DISC BRAKES ON VEHICLE DECELERATION

Braking system is one part of the equation that leads to the desired deceleration of the vehicle.Vehicle dynamics are equally important and should be optimized to achieve maximum deceleration of the vehicle.Whether the driver brakes and stops the vehicle in an emergency, it must be able to stop safely.This means that he does not harm himself or other traffic participants.Velocity makes braking more difficult because higher velocities require higher braking forces.When they are moving at high velocities, more braking force is needed to slow them down.High braking forces lead to high deceleration values.When high braking force is applied, the vehicle will decelerate very quickly, however, high decelerations affect the brakes.In order to slow down the vehicle, a very large braking force is applied, and the work performed will lead to a large amount of thermal energy in the brakes, which can cause them to overheat and thus endanger traffic safety.The paper will define the influence of disc brake thermal stress on vehicle deceleration for different initial velocities
